One trash day, I noticed that my cans had been returned to the front of my house. My first thought was to wonder whether it was an act of kindness from my trash collector (yeah, no). Or perhaps it was a nice neighbor or a fastidious poltergeist. But I didn’t have to guess, because I have a security camera that captured the event.The job of Wi-Fi security cameras is to capture video and make it easy to see what goes on around your home, not just in the moment but in the past too. But when you decide to get one, you have to choose how you want your camera to store video clips. Today’s security cameras provide two options: You can choose local storage, which lets you keep recordings in the camera or in your home (on another device), or you can elect to upload them to the cloud, where they are stored in data centers. We generally recommend cloud storage as the more foolproof option (you can read our thinking for details). But we recognize that cloud storage typically costs extra, in the form of a subscription, and maybe spying on your trash cans isn’t worth another monthly fee. Also, some people get the willies at the notion of having their video shared over the internet, even if it’s protected. If that describes you, here are our security camera picks that let you opt to store all recordings locally.
